HERNIAL TRUSS.

SPECIFICATION forming part of Letters Patent No. 648,368, dated April 24, 1900.

Application filed May 8, 1899.

To all whom it may concern:

Be it known that I, JAMES M. TARRANT, a citizen of the United States of America, residin g at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Hernia-Trusses; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification. I

My invention relates to improvements in hernia-trusses, myobject being to provide a device of this class which shall be simple in construction, economical in cost, and reliable,

. durable, and efficient in use; and to these ends the invention consists of the featu res,arrangements, and combinations hereinafter de-.

mentary edge view of the truss-plate, illus-' trating one of the slotted'lugs in which are journaled the spindles of the antifrictionrollers upon which the elastic bands are supported. Fig. 6 illustrates the lug with the spindles in place, a fragment of the roller being also shown. Fig. 7 illustrates the bearing-plate for use in connection with the construction shown in Fig. 3. Fig.8 shows thedouble-elastic-cord construction. Fig. 9is a longitudinal section showing the elastic cord and its protecting-sheath, the same being broken away in the middle. Fig; 10 is a section taken through the antifrictional roller and the spindle upon which it is journaled. Fig. 11 is a top view of the form of the device having a single pin for each pad. Fig. 12 is arear view of the truss-plate, or a view from the side opposite that upon which the pads are located.

Serial No. 716,053. No model.)

Similar reference characters indicate corre= sponding parts in the views.

Referring first to the construction shown in Figs. 1 and 2, let the numeral5 designate the truss-plate, whichis provided with four openings located near each extremity to receive a corresponding number ofsliding pins 6, upon which each truss-pad 7 is mounted. To the outer extremity of each set of these pins is pressure until the parts occupy the position shown by dotted lines in Fig. 1. When the pad is released from the inward pressure, the recoil of the elastic band returns the pad to its normal position.

' In the form of construction shown in Figs. 3, 11, and 12 the plate 5 is only provided with a single openi'ng, located near each extremity and adapted to receivea pin 6, square in cross-section, upon one extremity of which the pad is mounted. To the opposite exby means of a screw 16, which enters a threaded socket formed in the pin. The plate 15 bears against the rubber or elastic band 9 and performs the same function as the plate 8 in the other form of construction.

The extremities of the plate 5 are provided with openings 5 to facilitate the attachment of the extremities of the body-belt 18. To the trussplate 5, adjacent each bearing-plate 8, is attached a ring 19. To each of these rings is attached one extremity of an elastic cord 20, the other extremity of said cord be- Each cord 20 is surrounded by a tube 21, preferably composed of rubber and of such size that the cord 20 may move freely therein without the movement'of the tube, whose extremities are both free, whereby the tube,
